Equipping the compressor installation with an electric motor results in a hybrid installation with two drive options: electric and PTO. This smart combination can fulfil the demands of any client when it comes to CO2 or nitrogen emissions, and provides a significant noise reduction.
Hybrid drive
Motor placed in line with the compressor
In this setup, the electric motor is connected to the compressor using a flexible connection. If a PTO is used, the compressor is driven by a power band in combination with our aluminium, maintenance-free bearing block and automatic tensioning unit.
This setup requires 1600mm of room.
Motor placed between chassis
In this setup, the electric motor is placed in the chassis. The motor and compressor are connected using V-belts, with the motor serving as a bearing block. The PTO shaft is mounted on the flange of the electric motor. In order to correctly tension the V-belts, a tension pulley is used. The required room for this installation is 1000mm. However, enough room should remain in the chassis to place the electric motor.
Compressed air cooler
Air cooling is achieved by means of an aluminium fan directly connected to the compressor. This will increase operating reliability and there is no electrical fan needed.
Especially for combustible or temperature sensitive products the installation is equipped with a compressed air cooler. The compressed air cooler is completely made of aluminium and cools the compressed air approximately 100°C. Depending on intake temperature, pressure and capacity the outlet temperature is roughly 65°C.
Silencers and filter
The RTI/MMT aluminium pulsation silencer is constructed based on the volume size and is equipped with a (steered) pressure relief valve and a built in non-return valve.
The aluminium filter unit is equipped with a high-quality and moisture resistant 5 μm RTI/Mira air filter/intake silencer.
By applying these parts in combination with aluminium pipes and a cooling installation, the installation will meet all requirements set by the chemical and food industry.
OPTIONS
The RTI installation can be tailored to your wishes with several options and additions.
Rotary coupling
Specifically for feed there is the possibility of a rotary coupling in front of the fifth wheel hitch. By using a rotary coupling in front of the fifth wheel hitch the compressor hose can be connected to the semitrailer permanently.
High air intake
The compressor installation can be equipped with a high air intake developed by RTI. Air is drawn in at the top of the driver’s cab, this prevents the intake of dust and exhaust gasses.
The intake of cleaner and cooler air will increase the longevity of the air filter. The high air intake can also be adjusted to the Mobil Plastics requirements for air intake (MP requirements state that air should be drawn in at the top of the driver’s cab).
Air outlets
The standard outlets of an RTI installation are placed at the front of the cooler, the cold outlet at the top and the warm outlet at the bottom. You can also choose to have the outlets changed according to your wishes.
Compressed air cooler
To save space the compressed air cooler can be installed at the bottom of the installation. The minimum space required to mount the installation is 850 mm.
Other options
Flexible use of the installation can be attained by the following options:
- a blow-off silencer
- an extra pressure relief valve (high/low pressure)
- cold and warm air mixing
- a combination of the above
